Abstract
A system for resurfacing orthopedic joints by arthroscopic means. The system involves a method that includes the delivery of a curable biomaterial, and the use of minimally invasive means to prepare an injury site, and then deliver, cure and shape a curable biomaterial at the site of injury.
Claims17
A method for repairing or resurfacing the site of an injured articulating joint, the method comprising the steps of:
- (a) providing a curable biomaterial;
- and
- (b) performing the surreal steps of;
- (i) accessing and preparing the joint site for receipt of the biomaterial;
- ii) delivering a quantity of the curable biomaterial to the prepared joint site;
- (iii) curing the delivered biomaterial in such a manner that the cured biomaterial is permanently retained in apposition to the prepared site;
- and contouring the cured, retained biomaterial to achieve a desired conformation approximating that of the natural joint, wherein steps (i) through (iii) are each performed using minimally invasive surgical means.

A method for repairing or resurfacing the site of an injured articulating joint, the method comprising the steps of:
- (a) providing a flowable, curable biomaterial;
- hydrogel;
- (b) preparing an access site by means of an arthroscopic system comprising a fiberoptic scope and a biomaterial delivery cannula and inserting and directing a delivery cannula through the tissue access site to the site of joint injury;
- (c) delivering a quantity of the curable biomaterial through the cannula to the prepared joint site;
- (d) curing the delivered biomaterial in such a manner that the cured biomaterial is retained in apposition to the prepared joint site;
- and
- (e) contouring the cured biomaterial to achieve a desired conformation approximating that of the natural joint, wherein steps (b) through (e) are each performed using minimally invasive surgical means.
